Get the seat slot of the touch event. A seat slot is a non-negative seat wide unique identifier of an active touch point.

For events not of type @ref LIBINPUT_EVENT_TOUCH_DOWN, @ref LIBINPUT_EVENT_TOUCH_UP, @ref LIBINPUT_EVENT_TOUCH_MOTION or @ref LIBINPUT_EVENT_TOUCH_CANCEL, this function returns 0.

@note It is an application bug to call this function for events of type other than @ref LIBINPUT_EVENT_TOUCH_DOWN, @ref LIBINPUT_EVENT_TOUCH_UP, @ref LIBINPUT_EVENT_TOUCH_MOTION or @ref LIBINPUT_EVENT_TOUCH_CANCEL.

@return The seat slot of the touch event
